SPECIFICATION forming part of Letters Patent No. 679,319, dated July 30,1901. Application filed April 901- Serial No. 54,307. (No model.)

To rtZZ whom it may concern.-

Be itknown that we,AUGUsT KOY and JOHN KVETON, citizens of the UnitedStates, residing at Sealy, in the county of Austin and State of Texas,have invented a new and useful Insect-Destroyer, of which the followingis a specification.

This invention relates to insect-destroyers, and has special referenceto that type of machines which provide for the generation of poisonousfumes and the conducting thereof to growing crops or other points whereitmay be necessary to reach the insects to be destroyed.

To this end the invention has in view the construction of a fumigatorspecially designed as an exterminator for the cotton-boll weevil,although being well adapted for the extermination of prairie dogs, or,in fact, all classes of vermin which are destructive to crops ofdifferent kinds.

With these and many other objects in view, which will more readilyappear as the nature of the invention is better understood, the sameconsists in the novel construction, combination, and arrangement ofparts hereinafter more fully described, illustrated, and claimed.

The essential features of the invention involved in the novelarrangement and relation of parts are necessarily susceptible to somemodification without departing from the spirit or scope thereof; but thepreferred embodiment of the improvements is shown in the accompanyingdrawings, in which- Figure 1 is a perspective view of a portable insectdestroyer or exterminator constructed in accordance with the presentinvention. Fig. 2 is a top plan View of a portion of the machine. Fig. 3is a sectional view on the line 3 3 of Fig. 2, showing the interiorconstruction of the generating-drum, as well as the manner ofassociating the same with the blower-casing. Fig. 4, is a verticalcross-sectional view on the line 4 4 of Fig. 3.

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

In carrying out the present invention it is the purpose to arrange theworking parts thereof upon a suitable carrier, preferably in the form ofa wagon or truck, whereby the same may be readily transported from placeto place, as well as conveniently drawn over a field, especiallyin theextermination of the cotton-boll weevil. While any special type ofcarrying wagon or truck is not necessary to the successful carrying outof the invention, still an ordinary fiat-bed wagon, such as shown in thedrawings, has been found well adapted for the purpose.

Referring particularly to the drawings, the numeral 1 designates thecarrying wagon or truck, essentially comprising the usual front and rearaxles 2 and 3, fitted with the ordinary supporting or ground wheels 4and sustaining thereon an elevated bed or platform 5, upon which aremounted the main working parts of the machine.

The essential parts of the invention reside in a generator for thepoisonous fumes and a blower for forcing these fumes to the point ofuse, said generator and blower being designated,respectively,by thereference-numerals 6 and 7. The blower 7 comprises a circular casing 8and a rotary fan 9 working therein, said fan being of the type usuallytermed a blower-fan, to provide for forcing a windcurrent to any pointof distribution. In the present invention the blower-casing 8 isarranged in an upright position and is provided at the lower sidethereof with a rest-base 9, which is bolted or otherwise securelyfastened on top of the elevated bed or platform 5 of the carrier wagonor truck. The casing Sis further provided at one side thereof with anoffset bearing-bracket 10, provided with alined bearings 11, in which isjournaled a fan-shaft 12, to the inner end of which, within the'casing8, is rigidly fitted the rotary fan 9. The said rotary fan 9 is of anordinary construction and essentially consists of a plurality ofradially-disposed fan-blades 13, which not only create a suction fordrawing the gases or fumes into the casing, but also provide for theforcible expulsion thereof under pressure through the tangentialdischarge-spout 1 L, projecting from the rim of the blower-casing 8 andpreferably at the rear side thereof to permit of the convenient handlingof the distributing-pipes. The said fan-shaft 12,which extends exteriorto the casing 8, so as to have a firm journal-support in the bearings 11of the bracket 10, has fitted thereon between the said bearings abelt-pulley 15, over which passes a driving-belt 16, driven from a belt-Wheel 17, mounted upon a counter-shaft 18, supported in an elevatedposition above the bed or platform 5 in the bearings 19, provided at theupper end of a pair of supportingstandards 20, rigidly fastened andbraced to the wagon bed or platform in any convenient manner and arisinga suitable distance above the same to provide for the proper support ofthe belt-wheel 17 in vertical alinement with the pulley of thefan-shaft.

Various means may be resorted to for com municating motion to thecounter-shaft 18; but the means shown in the drawings are preferred.These means involve the employment of a driving-gear 21, in the form ofa skeleton gear ring detachably bolted by means of the clip orequivalent bolts 22 to the .inner side of one of the supporting orground wheels 4 of the carrying wagon or truck. The said driving-gear 21receives thereover an endless drive-chain 23, which also meshes with achain wheel or pinion 24 upon one end of the counter-shaft 18. Hencewhen the carrier wagon or truck 1 is in motion poweizwill be transmittedfrom one of the wheels thereof to the fan-shaft, thus providing forpositively rotating the blower-fan, with a consequent circulation andforcing out of the fumes.

The blower-casing 8 is provided in the side thereof opposite the bracket10, which supports the fan-shaft, with'the inlet-eye 25 and from thesame side thereof has projected therefrom an offset annularattaching-flange 26, which receives thereover the open end of thecylindrical generating drum 27. This generating-drum 27 is closed at oneend and open at the other, said open end being fitted, as explained,directly over the offset annular attaching-flange 26 of theblower-casing and secured thereto by means of the fastening rivets,bolts, or equivalent fastenings 28, thus providing means for firmlyuniting the generating-drum to one side of the blowercasing, so that thedrum and casing will be placed directly in communication with eachother, while at the same time the blower-casing will provide a supportfor the generatingdrum and obviate the necessity of individualsupporting means therefor.

The generating-drum 27 is preferably of a cylindrical form and hasfitted therein, contiguous to the adjacent side of the blowercasing 8, abafle-plate 29. This baffie-plate 29 is provided therein with aplurality of circulating-ports 30 for the fumes and confines between thesame and the said adjacent side of the blower-casing an air-chamber 31,with which communicates an annular series of draft-openings 32, arrangedin the same circular plane and piercing the joint connection between thegenerating-drum and the blowercasing 8. The said draft-openings 32 aredesigned to supply the necessary amount of associated with one of theopenings 32 and is pivotally mounted upon the exterior of thegenerating-drum contiguous to said opening, so that the same may bereadily moved upon its pivot to provide for covering or uncovering theopening, either entirely or partially, as may be desired.

Between the baffle-plate 29 and the closed end of the generating-drum27, opposite the inlet-eye of the blower-casing, the generatingdrum hasarranged horizontally therein the fire-grate 34, which grate is designedto support the fuel and also a removable chemicalcup 35. The saidchemical-cup 35 is of any suitable form, preferably of the open-toptype, and in the present invention is designed to have suitably attachedthereto the lower end of a carrying-stem 36, the upper end of which stemslidably extends through the flanged lid or cover 37, fitting in theupper end of the upright tubular entrance-dome 38, arising from the topside of the generatingdrum 27. The said upright tubular entrance- -dome38 preferably consists of a short section of piping suitably fitted tothe top of the generating-drum in line with a top opening therein tofacilitate the introduction of fuel and the manipulation of thechemical-cup 35. the generating-drum 27 is provided with an ash-door 39,which can be opened from time to time to provide for cleaning out thedrum from ashes or other accumulations.

,The fumes,which are drawn into the blowercasing and discharged throughthe spout 14 thereof, are forced into the delivery-pipe 40, fitted atone end in the spout 14 and carrying at its opposite end theoppositively-extending branch pipes 41, to each of which is fitted aflexible distributing tube or hose 42. The delivery-pipe 40 and itsbranches 41 are supported in a horizontal position on top of the truckor platform 5, while the tubes or hose 42 trail in rear of the truck andcan be pointed in any direction wherever it is desired to discharge thefumes.

In the operation of the machine with the truck traveling over the groundit will be understood that the fumes generated Within the drum 27 fromthe chemicals in the cup 35 are drawn through the circulating-ports 30of the baffle-plate into the air-chamber 31 and thence through theinlet-eye 25 into the blower-easing, from which the said fumes areexpelled through the piping described. In the use of the machine thegeneration of fumes may be stopped at any time by drawing the cup 35 upinto the dome 38 without removing the lid or cover 37 for the dome; butwhen it is neces- Beneath the plane of the fire-grate 34- sary toreplenish the fuel or the chemical within the cup the said lid or cover37 is removed therefrom, so that the chemical-cup may be drawn entirelyout through the dome and the fire-grate exposed for the introduction offresh fuel.

From the foregoing it is thought that the construction, operation,andmany advantages of the herein-described insect-destroyer orfumigating-machine will be readily apparent to those familiar with theart without further description, and it will be understood that variouschanges in the form, proportion, and minor details of description may beresorted to without departing from the principle or sacrificing any ofthe advantages of this invention.
